Copied/inspired from http://oreilly.com/pub/h/1968? (note that even the "bla" is the same)

Entirely possible that's the original source for the line to establish and listen from the connection. You can find that code in a lot of places though. Honestly couldn't tell you where I grabbed it from.

COPYPASTA! WATCH OUT, BAD SOCKET BAD SOCKET.
Seriously though, Python is horrible for the purpose of irc bots. I am a fan of python, but I WONT DO THAT.

Suggestion, Do not put a copyright claimer on some code you copy pasted. Bad idea.

How to make it with Tor network?

Why do you think that? I've written multiple fully featured IRC bots without any issues.
I'm curious about your point of view on Python being horrible for IRC bots.

nice script
